Always in progress, I have made several upgrades for the durability of the choker as well as a new safety feature. The USB charging port and switch are now enclosed, and the battery cable is removable to make it child proof and safe for travel.
You can also monitor the battery voltage via the super cool little LED indicator which seems to dance with the pulses of the plasma.
Up next: plasma titties. I have the concept and design in my head, I just need to make some time to work on it.
